For example, when you type <em>www.example.com<\/em>, the DNS helps convert this domain name to the corresponding IP address to send requests to the server. Therefore, <strong>configuring the DNS Server<\/strong> is extremely necessary to ensure everything works smoothly.<\/p>\n<ul>\n<li><strong>How does a DNS Server work?<\/strong> Every time an access request is sent, the DNS Server searches for and returns the IP address of the domain name.
